Abstract
A system to generate medical monitor alarm settings (10) which includes a normative analyzer (36) and/or observational analyzer (48) configured to receive (130) data from logs (32, 34) of a plurality of medical monitors (12), and generate (134, 138) one or more suggested alarm settings (26) based on a constructed model of the received log data.
Claims20
A system to generate medical monitor alarm settings, comprising:
- a plurality of medical monitors;
- a normative analyzer configured to:
- receive data from logs of the plurality of medical monitors, the received data including at least alarm settings for a plurality of monitored vital signs and alarm conditions including time averaged vital sign signal values, alarm settings for the plurality of monitored vital signs, and changed alarm settings for the plurality of monitored vital signs;
- and
- generate one or more suggested alarm settings based on a constructed model of the received log data.
A non-transitory computer-readable storage medium carrying software which controls one or more data processing devices to perform a method of generating medical monitor alarm settings, the method comprising:
- receiving log data from logs of a plurality of medical monitors, the received log data including at least changed alarm settings for a plurality of monitored vital signs;
- constructing a model of the received log data by at least a regression analysis of the changed alarm settings and vital sign signals;
- and
- generating one or more suggested alarm settings based on the constructed model of the received log data.
A system to monitor patient vital signs, comprising:
- a medical monitor configured to receive monitored vital signs for at least one patient, vital sign signal values for a plurality of monitored vital signs, changed alarm settings for the plurality of monitored vital signs, vital sign signal values with corresponding changes to alarm settings for the plurality of monitored vital signs, and alarm conditions including time averaged vital sign signal values and alarm settings for the plurality of monitored vital signs, and includes a plurality of sets of alarm settings defined according to a constructed normative model of data from selected medical monitors, the model being constructed by a regression analysis of the settings and vital sign signals, a correlation of at least one of the settings, the vital sign signals, and changed alarm settings, a cross-correlation of the settings for a plurality of vital signs, and an analysis of variance of the settings and vital sign signals, each set of alarm setting includes at least one of an upper and a lower limit for a plurality of monitored vital signs;
- and
- an observational analyzer configured to receive the plurality of monitored vital signs in an alarm condition according to a first set of alarm settings and return a recommended second set of alarm settings which places the plurality of monitored vital signs in a non-alarm condition.
